摘要
在现代战争中,战场电磁环境随着作战双方电子战的开展不断发生变化,它的变化严重影响着战场各种通信设施的正常工作,因此,有必要研究不同地形环境条件下电波的传输特性。详细论述了不同地形环境下发射信号路径损耗计算模型,并采用数字高程模型(DEM)空间分析技术对局域范围内的发射信号中值路径损耗进行建模,为实现复杂地形条件下的电磁环境分析提供了一种有效的建模仿真方法。
In modern wars, the battle electromagnetic environment changes with the situation of elec- tronic war and impacts on the communication systems. As a result, it is necessary for to study the wave transmit character under different topographical conditions. The transmit path loss models for different topographical conditions are discussed and constructed based on the digital elevation model（DEM） data, which provides an effective simulation for the electromagnetic environment analysis
